Marine Weather and Tide Forecast for Darwin, CA

DISCUSSION
Today through Sunday.

The region is drying out this week as a ridge of high pressure builds over the Desert Southwest. That said, some moisture still remains over the region today, so expect partly cloudy skies this afternoon across the Mojave Desert and southern Great Basin. A few of these clouds may (0 to 10 percent chance) build into light showers, with a very slight (0 to 5 percent) chance of a lightning strike. Otherwise, temperatures will peak on Wednesday and Thursday as afternoon highs climb to 5 to 7 degrees above-normal and overnight/morning lows approach daily records. Though these afternoon temperatures are not incredibly impressive by August standards, many locations will experience overnight lows in the upper 80s to low 90s. This type of heat exhausts both people and infrastructure that rely on sufficient overnight cooling.
Particularly vulnerable populations include those without functioning air conditioning, those working outdoors, and those who are unhoused. Moisture will return to the region late-week, which will initially make the heat feel more oppressive before heights fall and temperatures decrease over the weekend.

Late-week into the weekend, a Pacific trough will push the aforementioned area of high pressure eastward, which will return the funnel of monsoonal moisture from northern Mexico into the Desert Southwest. The extent to which the high pressure pushes east will impact timing and placement of precipitation chances, so stay tuned to the forecast if you have weekend outdoor plans.
